This is a newer version of an older idea of mine and it has a very theoretical approach that i'm sure many won't agree with. I kept thinking on what masturbation means and how bizarre it is when you think about what is really happening. Whether you watch porn and masturbate (which is really bad), or just masturbate to your fantasy, the point is that you still "fake sex". Most of the new "sexual theory" likes to state that masturbation is somehow a separate entity from sex but i find that to be erroneous at best. Masturbation merely mimics sex, it's not "self exploration" or whatever the term of choice is now. The thing is your body couldn't get aroused, get and erection, feel pleasure and your penis wouldn't end up ejaculating if your body/mind didn't register the experience as "sex with a woman". You're just tricking your body/mind to think it's having sex and you're providing the illusion (images and touches) but at the end of the line it's just "pretend sex". The term "masturbation" takes away this undeniable truth. Now, since sex is always a paired activity, you can't do it by yourself, you need a partner. This "partner" is your hand usually which represents the woman stimulating you. But what does that mean? It means that you have to "split" in two persons - there's the male you who "feels" the "woman" and there's the "woman" you that "stimulates" the man. This is in my opinion extremely damaging because you stop being the man only and start being a woman (or vice-versa if you're a woman). If you think about it in terms of sensations you get, you as the "man" get like 10% of the sensation of a real vagina/mouth etc while you as the "woman", though your hand, get 100% the sensation of stroking a real penis. This becomes even more problematic if you watch "boy-girl porn" and when you see a woman manipulating a dick while you're stroking your own, pairing the sensations your get (and stroking a dick is the more genuine sensation), implies that you're actually the woman in porn, not the man. Basically, you are manipulating the penis and you see a woman manipulating the penis, therefore you are the woman.
